CLASSIFIED RESUME OF ORGANISMS OBSERVED 307 



three to five inches long, in our trawling nets, and smaller 

 ones more frequently; never, however, have we caught one 

 even approaching in size those listed above. 



Class CEPHALOPODA 



Order dibranchiata 



Squids were seen about a score of times from 200 to 2900 

 feet. They measured from two inches to two feet in length, 

 and the body color varied from white and pink to red and 

 reddish brown. The majority of those observed below 600 

 feet had light organs — blue, red, or green — scattered over 

 the whole body or encircling the eye. The illumination 

 seemed to be steady, not intermittent. The majority of 

 squids were single, but occasionally several swam together, 

 and twice large schools appeared. They swam more slowly 

 than any of the other large animals. The following observa- 

 tions were made on some of the individuals most clearly 

 seen, and are sufficiently varied to warrant publication: 



200 feet. Two. Small. Not together. 



3^0 feet. One. Five-inch. Red. Shot past. 



400 feet. One. Two-inch. Silvery. 



440 feet. One. Two-inch. Silvery. 



^00 feet. One. Luminous, with head-lights. 



900 feet. Twenty or thirty in a mass. Each twenty-four 

 inches. They had pale bluish lights, with two enormous 

 lights in front which were reddish. Small lights surrounded 

 the large head-lights. 



900 feet. One. Four-inch. Through light. 

 1000 feet. One. Very large. White. In beam.
